Public bug reported:
Binary package hint: linux-image-2.6.22-11-generic
Using kernel linux-image-2.6.22-10-generic I could not change the
backlight intensity on my Thinkpad T60, using the "Power Manager
Brightness applet. When I went into /proc/acpi/video, I noticed there
are two entries named "VID":
$ ls -li /proc/acpi/video/
total 0
4026532187 dr-xr-xr-x 5 root root 0 2007-09-09 12:42 VID
4026532187 dr-xr-xr-x 5 root root 0 2007-09-09 12:42 VID
When I echoed a number in /proc/acpi/video/VID/LCD0/brightness, it
changed the brightness. I don't know if the double entries confused the
applet or not.
With linux-image-2.6.22-11-generic, I can change the brightness using
the applet, but the two entries are still there.
